The Mather Byles letterbooks are held as Volume 25 of the Winslow Family fonds. The five letterbooks contain holographic copies of letters written by Mather Byles to Edward Winslow during 1784-1786 when Byles was in Halifax and Saint John. Byles informs Winslow of events in Halifax as they occur and thanks Winslow for his support on both a financial and influential level.

Arrangement is chronological.

Much of the material relating to the history of the history of the congregations before 1933 was destroyed in a fire. Most of the surviving records date from 1949 and were found in 1990 in the balcony of the synagogue. Extensive records of correspondence, annual reports, minutes, financial records, and membership lists were among what was found. There is also a large section of information available on bat/bat mitzvah, marriage and burial records for the genealogist. The cemetery records are the most complete as a database of all burials in the Shaarei Zedek Cemetery was compiled between 1997 and 2011. Material on these lifecycle events generally comes from personal memorabilia and newspaper records. A section on Jewish traditions and holidays is appended to show how these have been observed in this community and elsewhere.

Records for the communities in Moncton and Fredericton are very limited and include information found in public records including newspapers.
